Although I generally always mess with a recipe, even the first time I use it, this muffin recipe is incredibly simple and flexible. I have included almost exactly the ingredients and proportions as in the original, and over time I have played with the berries, the spices, the nuts, the sour and the flour.
Got a gluten and nut allergy? Swap out the nut flour and nuts for a gluten-free flour and some other grain.
Got lactose intolerance? Swap our the sour for a yogurt substitute.
